Throughout the drawing similar reference nu? merals refer to like parts in the diierentvews. Thereis shownin Figure 1 asmoking device or appliance having a'smoking material receptacle l provided with a neck 2 which has secured there# to anintermediate stem'member 3, the opposites@ end ofthe' latter being engaged by a stem 4. A mouthpiece generally designated by 5 is also shownassociated with the smoking device, the end thereof being engaged by an-end of the stem.

' Asit may be observed the intermediate stem` 85,- member 3 is provided with reduced neck 'portions 6 and 7 which engage respectively the end of the neck 2 and the end of the stemY 4. Thediameters of the reduced portions are such that a tight t between them'and the parts just mentioned is 90'l provided. A similar attaching feature is em` ployed in securing the mouthpiece to the stem, Y the grip portion 8 thereof being likewise provided with a reduced neck portion 9 which engages anL end of the stem. It will be appreciated that by 951 i the construction just described the principal parts of the device may be readily detached from one another and afterwardsV assembled.

For the purpose of conducting smoke fromV the smoking material receptacle to the mouthpiece, 100 the neck, intermediate stem member, stem andV mouthpiece are provided with suitable smoke con-` ducting passages. For example, the neck 2 is provided with a passageway 10 extending there through* and communicating' with the bowl 1. 195

Besides the passageway 10 provided in the neck portion of the bowl, it may be observed that the lower part of the neck is formed with a compartment or chamber 12 which is unconnected from the bowl and from the passageway. The purpose of this compartment will hereinafter appear.

The reduced end 6 of the intermediate stem member 3 is provided with an enlarged opening 13 communicating with a compartment or chamber 14 formed in the intermediate stem member. It may be observed that the passageway having the smoke duct 11 positioned therein communicates with .the opening 13. If desired, the ends of the passageway 10 may be formed with a flange 10 as shown, so that the ends of the passageway and smoke duct are flush with the face of the intermediate stem member. It will be appreciated, however, that other constructions for positioning the smoke duct so that it communicates with the passageway 13 and consequently the chamber 14 may be employed if desired without departing from the spirit of the invention.

The forward face of the reduced portion 6 is also provided with a passageway 15 which communicates with the compartment 12 formed in` the bowl neck. As is shown a conduit 16 having a lip portion 17 is positioned in the passageway 15 so that the end of the conduit provided with the lip portion is within the compartment 12. It should be noted that by this construction, the purpose of which will hereinafter appear, the conduit 16 is positioned substantially in the center between the top and bottom of the chamber or compartment 12.

For the purpose of conducting the smoke from the compartment in the intermediate stem member, a passageway extends from the rearward end of this compartment through the intermediate member and has positioned therein a smoke duct 18.` It should be noted that the longitudinal center lines of the smoke ducts 11 and 18 are out of alignment with each other as well as being out of alignment with the conduit 16. In this construction the smoke duct 1l is near the top of the chamber 14, the conduit 16 vnear the bottom ofthe chamber and the duct 18 intermediately placed between them. With reference to Figure 5 and Figure 2, it will be apparent that the smokerduct 18 is in the same horizontal plane as the longitudinal axis of the stern, being, as shown in Figure 5, to the left ofthe vertical axis of the stem. 1 y

As previously pointed out there is secured to the end of the intermediate member 3 most distant from the bore, a stem 4. VThis stem has formed therein a partition 19 which may either be integral therewith or secured therein in any desired manner.v The partition is provided with a plurality of openings through one oi which passes the smoke duct 18. By the provision of the partition it will be appreciated that the stern is divided into a forward compartment 20 and a rearward compartment 21, the duct 18 being of suiiicient length to extend Aentirely through the forward compartment and to project for a considerable distance into the rearward compartment.

,In the other opening of the partition, there is positioned a conduit 22'provided with a lip portion 23. The conduit 22 is substantially similar in all respects to the conduit 16 previously described, and provides a means of communication between the rearward compartmentZl and the Yforward compartment 20 of therstern. As in the case of the conduit 16 the end of the conduit 22 is provided with a lip 278 which extends,

into the compartment or chamber of the stem nearest the pipe bowl. It should be observed that the conduit 22 provides means of communication between the compartments 21 and 20 which is entirely separated and unconnected from the smoke duct 18. As will presently appear any liquids in the compartment 21 will be conducted through the conduit 22 into the forward compartment 20, while smoke will not enter the forward compartment.

VThe stem 5 associated with the smoking device is provided with a grip portion 8 having the usual flanges formed upon the mouth end thereof. Through the grip portion 8 there extends a passageway having a uniform bore adapted to have inserted therein a tubular moisture absorbing member 24 which is maintained therein by frictional engagement with the walls of the grip piece. The moisture absorbing member is provided with a passageway through which the smoke is conducted from the smoke compartment 21 to the mouth of the smoker.

it may be observed that the moisture absorbing member 24 is of a length sufficient to extend entirely through its encasing grip piece and to proend of the moisture absorbing member 24 is caused to overlap the end of the smoke duct 18. It should be noted that the moisture absorbing member 24 is entirely unconnected with the smoke duct 18 and moreover these two members overlap without touching each other.

While the construction disclosed has shown a This feature is clearly shown in Figure 2 and by such construction the` Sil horizontal type of overlap wherein the passageway in the mouthpiece for the moisture absorbing member is angularly disposed with respect to the longitudinal center line of the former, it will be appreciated thatA this passageway may be so formed as to be parallel to the longitudinal axis of the mouthpiece. Likewise a vertical type of overlap could be readily provided. In this instance either the vertical position of the smoke duct 18 or the vertical position of the moisture absorbing member 24 as shown in Figure 1, would be raised or lowered `so -thatthe ends of one of these members would be over the end of the other. With the vertical type of overlap it would be unnecessary to shift the horizontal position of the moisture absorbing member and the smoke duct 18 as both of them could lie in a vertical plane passing through the longitudinal axis of the smoking device.

As in the case of the smoke ducts and conduit which have their ends positioned within the chamber 14, it is to be noted that the smoke duct 18, moisture absorbing member 24 and conduit 22 within and communicating with the compartment 21 have their bores entirely out of coincidence with each other and furthermore are unconnected "l be made up of phenolic condensation products or other equivalent material, as well as mouthpiece 8; and the moisture absorbing member 24-may be formed of. a suitable porous and absorptive material such as wood,-either seasoned maple or seasoned briar being preferable.

The bowl 1 is lled with tobacco or other smoking material which is ignited in the usual manner. Upon the smoker drawing. upon the mouthpiece smoke from the smoking material recept cle s drawn through the duct 11,-forward compartment 14, smoke duct 18 into the rearward compartment 21 and finally through the moisture absorbing member 24 to the mouth of the smoker. As the smoke passes through they conduit 11, Vapor carried therein is condensed and a further condensation eiiect occurs within the compartment 14 after which the `smoke is drawn through the conduit 18 and into the compartment 2l, further condensation occurring` within the last mentioned zones. Liquids condensed in the conduit ll drop into the compartment 15 and together with liquids condensed in the'compartinent itself and any liquids injected vinto the. compartment through conduit 18 are conductedinto the drain age chamber 12 where they are-entirely-separated from the I smoke.V Similarly, liquids condensed in the smoke duct 18 and in the rearward compartment 21 as well as liquids injected into the pipe through the moisture absorbing member, are collected at the bottom of the rearward compartment and are vseparated therefrom. by being 'conducted through the conduit 22 and into y the drainage unit 20. l

PTA

It has been previously pointedout that `the smoke ducts may be oi glass, while the intermediate stem and the stem proper may be formed of a phenolic condensation product, or other simi-A lar material.. It should be noted that these mem- 'i bers are pro-vided with relatively thick' walls.

While the preferred substances used in the formation of these members may be poor heat con-v ductors, their heat absorbing capacity due to their mass and thelarge surface or contact area L wh`ch they present to the smoke'will successfully effect the desred condensation of` thev vapor: Moreover, it will be appreciated that these 'sub-1 stances possess relatively'hig'h specic heats-andvr because of the mass of the members which they vform, there will be a subtantial continual ab sorption of heat from the smoke during the whole time of a pipe smoking.

While a certain amount of condensation occurs with'n each of the smoke ducts, it will be underjstood that this amount is small when compared with that occurring in the condensation chamber 14 and in the condensation chamber 21. 1t should be noted that the smoke, when leaving the rst condensation chamber 14 is subjected to a ,urther condensation in the smoke duct 18, and

a substantially complete condensation of the vapor carried thereby occurs within the condensa-tion chamber 2l.

Liquidscontained in the compartment 14 are prevented from entering the smoke duct 18 bement will be conducted through the conduit 16 and into the drainage chamber i2 where they are separated and substantially prevented from seeping back into the .forward condensation chamber by reason of the position of the conduit 16 with respect to the floor of the drainage unit.`

Liquids entering the compartment 14 through the smoke duct 18 will be similarly conducted to the drainage unit 12.Y

In operation-any liquids'condensed in the rear- Vtained in the condensation chamber are prevented from reaching the smoke duct 18 and the moisture'absorbing member 24 because of their elevations above the floor level of the stern. 'i As is-wellA kno-wn, it Afrequently occurs that the smoker ejects saliva into the mouthpiece ofv the pipe. vBy reason of the nature of theabsorbing member this will be substantially prevented. Should,l however, any such liquids reach the'inner end vof the moisture absorbing member they would drop,"by reason of gravity,to= the bottom of the chamber 21 where they vwould be conducted i'n amanner similar to that described, into the drainage unit 20 and there collected. It should benoted that the smoke conduit and the moisture absorbing member are out of coincidence with each other and that these two parts overlap. rThis construction besides allowing the length of the pipe to be considerably shortened, positively prevents any liquid being drawn from the smoke-duct into the mouth.

From 'an inspection -of Figure l it may be observed that none of the smoke passes through thev drainage compartments as it is separated from the compartment 20 by reason of the enclosing duct 18, and-entrance into the `drainage compartment l2 is substantially preventedby the drainage units 12 and 20. -Thus the liquids and filth formed and/or injected into the pipe are entirelyseparated from the smoke so that the latter reaches the smokers mouth in a dry condition yfree fromv contaminating substances.

The smoke in a substantially dry condition is drawn from the rearward condensation chamber through the tubular moisture absorbing member and directly into the smokers mouth. It has been pointed out thatthe moisture absorbing member is constructed of wood. While such a substance possesses a relatively high specic heat, vthe mass of the member formed therewith is small7 and moreover the other factor favorable to the occurrence of condensation, namely, a large contact area for the smoke within the moisture absorbing member is entirely lacking. This is apparent upon considering the bore area of the moisture absorbing member itself. It will hence be well understood that substantially no condensation occurs therein. Condensation in the bore of the member 24 is further limited as the smoke passing therethrough is in a substantially dry condition since by condensation, in the smoke ducts 1l and 18 and in the compartments 14 and 21, practically all of the condensible vapors carried thereby have been removed.

When it is desired to clean the pipe, the mouthpiece i-s removed from the stem by the exertion of a detaching force and the stem may be similarly disengaged from the intermediate stem member. Likewise the intermediate stem memtioning the smoke ducts within the smoking defrequently changed.

ber may be removed from its engagement with the neck of the smoking material receptacle.

The purpose of forming the opening 13 with a large periphery will now become apparent. By this meansthe drying out of the passageway 13 and the chamber 14, in the intermediate stem member, is readily facilitated because of the large amount or" air that may enter therein after the intermediate stem member has been detached from the smoking device.

It will be apparent that my novel pipe stem construction may readily be adapted to a cigar holder as shown in Fig. 8, wherein the correspending elements are identified by the same numerals as the pipe stem described, except the stem is shown -terminating with a recess 25 for receiving the end of a cigar, or if the recess is of less diameter, a cigarette.

It should be noted that the moisture absorbing member of the mouthpiece is so constructed as to be removable from its encasing member or grip piece. The moisture absorbing member may thus be permitted to dry out while a new member is inserted in its place and used therefor."

The smoking device may be so constructed as to permit the smoke ducts and conduits within the stem, intermediate stem member and neck of the smoking material receptacle to be readily removed after these parts have been detached as previously described. If desired, instead of posivice 'so that they may be readily detached there- .from after the parts have been separated, they ,ducts are of glass, both of which materials lendv 'of these parts it is apparent ythat the reverse opthemselves toI easy cleansing. In the assembly eraticns are gone through. Obviously, in the construction shown, cleansing operations need be undertaken only at infrequent intervals, particularly when the moisture absorbing member is While Il have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not conne myself to the precise details of construction herein set forth, by way oai-illustration, as it is apparent that many changes and variations may be made therein, by those skilled in theV art, without departing from the spirit o the invention, or exceeding the scope of the appended claims.
